I put the profiles from thunderbird on the old computer into dropbox. But when I tried to put them onto the new laptop that file turned out to be empty even though it said it was 15GB. I couldn't get any addresses off it and now the old computer has been wiped and returned already

re: I put the profiles from thunderbird on the old computer into dropbox. I need to know what folder you are getting off dropbox as it is important and can make a difference. What exactly have you got on dropbox ? Did you copy/backup the 'Thunderbird' folder to dropbox ? Meaning this Thunderbird folder : C://Users/User name/Appdata/Roaming/Thunderbird OR Did you just copy the actual 'profile name' folders to dropbox ? Profile name folders are located in the 'Profiles' folder: C://Users/User name/Appdata/Roaming/Thunderbird/Profiles/'profile name' The 'profile name' folders that look similar to this: 'abc1245t.default' or 'abc1245t.default-release '
